Answer:
x= 8.5, 2x=17, (9x+5)=81.5
Step-by-step explanation:
since the sum of the interior angles of a triangle is 180 degrees, you must add all of the angles and set them equal 180:
next distribute the 2 to 9x + 5.
next combine like terms (2x and 18x) and subtract 10 from 180.
finally, divide 170 by twenty.
the final answer is x=8.5
once x is determined, you can solve 2x and 9x+5.

Answer:
Step-by-step explanation:
A linear equation is written as , "m" being the slope and "b" being the y-intercept.
The slope is how many times you rise/run in order to get from one point on the line to the next. You rise (go up/down) 1 unit and run (go left/right) 3 units. Plug in the numbers and you get 1/3.
The y-intercept is where the graph lands on the y-axis, which is 4.
